I have read the LGB. The diagram you offered up would confuse me because it looks fixed. Note the "At least."

Oooh missed that, silly me. In that case it depends on how many players are left after you take out those two. If there aren't too many, there's probably a "set" # of cases that could happen - I'd probably try to diagram each case and figure time lost here will be gained when answering the questions.

It probably also depends on what the other conditions are, since that can restrict what can happen too as well.
